PART NO. 37-6120A 9934 INSTALLATION REMOVE OLD THERMOSTAT 1. Shut off electricity at the main fuse box until installation is complete. Ensure that electrical power is disconnected. 2. Remove the front cover of the old thermostat. With wires still attached, remove wall plate from the wall. If the old thermostat has a wall mounting plate, remove the thermostat and the wall mounting plate as an assembly. 3. Identify each wire attached to the old thermostat using the labels enclosed with the new thermostat. 4. Disconnect the wires from old thermostat one at a time. DO NOT LET WIRES FALL BACK INTO THE WALL. 5. Install new thermostat using the following procedures. W903 CUT TO DEFEAT EMR GAS ELECTRIC PRE-INSTALLATION SET-UP 1. Remove the packing material from the thermostat. 2. This thermostat is configured from the factory to operate a heat/cool, fossil fuel (gas, oil, etc.), forced air system. It is configured correctly for any system that DOES NOT require the thermostat to energize the fan on a call for heat. If your system is an electric heat or heat-pump system that REQUIRES the thermostat to turn on the fan on a call for heat, locate the GAS/ELECTRIC switch on the back of the thermostat (see fig. 1) and switch it to the ELECTRIC position. This will allow the thermostat to energize the fan immediately on a call for heat. If you are unsure if the heating/ cooling system requires the thermostat to control the fan, contact a qualified heating and air conditioning service person. 3. Two jumpers are also located on the back of the thermostat, so that you may customize the thermostat to meet your individual preference (see fig. 1). In most applications, the factory jumper settings provide the most comfortable and convenient thermostat operation. Jumper wire W905 determines how fast the system cycles on and off, based on temperature change. As shipped from the factory, the thermostat will maintain a very consistent room temperature, usually within 1°F of the thermostat setting. To achieve a slower on and off cycle, providing a slightly wider temperature span, cut and separate jumper wire W905. Jumper wire W903 controls the Energy Management Recovery (EMR) feature. EMR allows the thermostat to energize the heating system up to 30 minutes before the time programmed into the thermostat. The thermostat will then energize the system to gradually raise the temperature to your programmed temperature by using the most efficient stage of heat practical. For example, assume that the thermostat is programmed overnight to 66°F and the room temperature is 66°. If the next program is 7 AM, 70°F (an increase of 4°), the thermostat will start the system 30 minutes before 7 AM. If the temperature in the room is within 2°F of your next programmed temperature, the thermostat will not start the system early. DO NOT clip jumper wire W903 unless you wish to permanently disable the EMR feature. 2 W905 CUT FOR LONGER CYCLES Figure 1.

Gently remove the cover by pulling it straight off the base. Forcing or prying on the unit may cause damage to the unit. 2. Remove the battery tab. With the batteries installed, the Armchair Programming feature allows you to program the thermostat before installing it on the wall. 3. Pull wires through the hole in the thermostat base and place the base over the hole in the wall. Mark mounting hole locations on the wall using the base as a template. 4. Move the base out of the way. Drill mounting holes. 5. Fasten the base loosely to the wall, as shown in fig. 2, using two mounting screws. Place a level against the bottom of the base, adjust until level, and then tighten the screws. (Leveling is for appearance only and will not affect thermostat operation.) If you are using existing mounting holes, or if the holes drilled are too large and do not allow you to tighten the base snugly, use plastic screw anchors to secure the base. 6. Check that the system is turned off. Connect the wires beneath the terminal screws on the base using the appropriate wiring diagram (see figs. 3 through 5). 7. Push excess wire into wall and plug hole with a fire-resistant material (such as fiberglass insulation) to prevent drafts from affecting thermostat operation. (Instructions continue on page 4.)

OPERATING FEATURES Now that you are familiar with the thermostat buttons and display, read the following information to learn about the many features of the thermostat. • SIMULTANEOUS HEATING/COOLING PROGRAM STORAGE — When programming, you can enter both your heating and cooling programs at the same time. There is no need to reprogram the thermostat at the beginning of each season. • AUTOMATIC CHANGEOVER —If you have a heating/ cooling system, you can set the thermostat to automatically switch from heat to cool as needed to maintain setpoint temperature. To select this mode, press SYSTEM button until AUTO is displayed along with HEAT or COOL, identifying the program automatically selected. In AUTO mode, pressing and at the same time will change the displayed setpoint temperature to the setpoint of the other mode (HEAT or COOL). This allows you to change both the HEAT and COOL setpoints, if desired. • TOTAL KEYPAD LOCKOUT — This security feature allows you to lock out the thermostat buttons to prevent unauthorized tampering. To select this feature after programming, press SET TIME and RUN PRGM buttons at the same time and hold until LK is displayed. To unlock the thermostat, press SET TIME and RUN PRGM buttons at the same time until LK is no longer displayed. • TEMPERATURE OVERRIDE — Press or until the display shows the temperature you want. The thermostat will override current programming and keep the room temperature at the selected temperature until the next program period begins. Then the thermostat will automatically revert to the program. • HOLD TEMPERATURE — The thermostat can hold any temperature within its range for an indefinite period, without reverting to the programmed temperature. Press the HOLD TEMP button. HOLD will be displayed. Then choose the desired hold temperature by pressing or . The ther- mostat will hold the room temperature at the selected setting until you press RUN PRGM button to start program operation again. • °F/°C CONVERTIBILITY — Press SET TIME and HOLD TEMP buttons until the temperature display is in Celsius. To display Fahrenheit, repeat the process. (Instructions continue on page 6.) 5 • TEMPERATURE DISPLAY ADJUSTMENT — Your new thermostat has been accurately set in our factory. However, if you wish, you may adjust your new thermostat temperature display to match your old thermostat. This can be accomplished (within a ±4°F range) as follows: 1. Press VIEW PRGM and HOLD TEMP buttons at the same time. 2. Press or to adjust the displayed temperature to your desired setting. 3. Press RUN PRGM to resume normal program operation. PROGRAMMING YOUR THERMOSTAT Now you are ready to program your thermostat. This section will help you plan your thermostat’s program to meet your needs. For maximum comfort and efficiency, keep the following guidelines in mind when planning your program. • When heating (cooling) your building, program the temperatures to be cooler (warmer) when the building is vacant or during periods of low activity. • During early morning hours, the need for cooling is usually minimal. Look at the factory preprogrammed times and temperatures shown below. If this program will suit your needs, simply press the RUN PRGM button to begin running the factory preset program.
